Benefits of technology
[0007]The present invention provides a method of operation of a communication system including: calculating a shift distance of a received signal having a distortion; calculating an approximate likelihood of the received signal matching a transmitted signal from the shift distance; determining a bias factor from the distortion; and selecting a determined modulation maximizing a combination of the approximate likelihood and the bias factor for communicating with a device.
Problems solved by technology
However, signals used in mobile communication effectively experience various types of interference from numerous sources, which affect the quality and speed of the accessible data.
Solutions to these problems have been long sought but prior developments have not taught or suggested any solutions and, thus, solutions to these problems have long eluded those skilled in the art.
